説明

　Sets the drawing clip rectangle for the layer.
　Drawing on the layer is limited to the drawing clip rectangle (the part outside the rectangle is not drawn). However, some methods, such as Layer.flipLR and Layer.flipUD, are not affected by the drawing clip rectangle.
　By default, the clip rectangle is set to the entire layer image area (it can be drawn on the entire layer).
　The drawing clip rectangle returns to the initial value when the image is read, the image size is changed, or the display type of the layer is changed.
　Call this method with no arguments to reset the drawing clip rectangle to its initial value.
